DESCRIPTION

Setra's Model 267 and 267MR pressure transducers sense gauge (static) or differential pressure in air pressure ranges as low as 0.1"WC Full Scale up to 100"WC.

FEATURES

Model 267MR Offers Multi-Range Capability, 6 Field Selectable Ranges via Dip Switches, and Field Selectable 0-5 or 0-10 VDC Output

Model 267 Offers an Optional 3 1/2 Digit LCD Display with a 0.5% FS Standard Accuracy

NEMA 4/IP65 Rated Housing

Optional Accuracies as High as 0.25% FS

24 VAC or 24 VDC Excitation

PG-9, PG13.5 or Conduit Electrical Termination Integral Static Pressure Probe

Ranges as low as 0.1 in. W.C. (25 Pa) Meets CE Conformance Standards

The Model 267 gauge pressure transducer is offered in a high level voltage or 4 to 20 mA output and is available with a static pressure probe for installation directly onto the duct. The 0.25" diameter pressure probe is made of sturdy extruded aluminum and is designed with baffles to prevent velocity pressure errors. This unit is also available with an LCD display.

The 267MR multi-range transducer offers 6 field selectable pressure ranges (bidirectional and unidirectional), and field configurable outputs of 0 to 5 VDC, 0 to 10 VDC, and 4 to 20 mA. With the flip of a switch the user can field calibrate the unit and be assured of optimum performance.
